Always inspect the ultrasound probe cap, cover and cable before using it with the Site~Rite IV Scanner. Do not use the probe if the cap is cracked or damaged. Do not allow the probe liquid or liquid vapor to contact the eyes, skin, clothing or room furnishings. The fluid can be irritating to the skin and eyes and may damage furniture finishes. In case of contact, immediately rinse the area with water. Do not pull the cable to disconnect the probe-connector from the scanner. Pulling the cable may damage the cable, cable connection or scanner. Do not twist or bend the cable in excess of that required during normal use of the probe. Excessive twisting or bending of the cable may cause failure or intermittent or unpredictable operation. When disinfecting the probes with a liquid disinfectant, do not soak the probe cable, cable bend relief or probe connector. Doing so may damage the probe. Hot water (in excess of 113°F or 45°C) may damage the probe. Do not expose the probe to direct sunlight for an extended period of time. Excessive heat from the sun may damage the probe. Before you connect the A/C adapter to or disconnect the A/C adapter from the Site~Rite IV Scanner, verify that the A/C adapter is not plugged into a wall socket. Check the alignment of the 7.5 MHz and 9.0 MHz fluid standoff probes at least once a month, or after a probe has experienced any mechanical impact. Do not use a misaligned probe for needle guidance. For the alignment test, see Chapter 5.5, Periodic Probe Testing. Only apply commercially available ultrasonic couplant, which has been specifically formulated for use in medical applications, to the acoustic window (or face) of the probe. Use water or rubbing alcohol and a soft cloth to remove couplant from the acoustic window (or face) of the probe. Do not allow ultrasonic couplant to dry on the acoustic window (or face) of the probe. If the couplant should dry, use water or rubbing alcohol and a soft cloth to remove it. Never use a tool of any kind to remove dry couplant from the acoustic window (or face) of the probe. Some commercially available probe covers contain latex. Natural rubber latex may cause allergic reactions. Refer to the US FDA alert titled: "Medical Alert: Allergic Reactions to Latex-Containing Medical Devices." Bard Access Systems distributes sterile probe covers and needle guide kits that do not contain latex. Do not force the Probe connector. Damage to the connector and system could result. Use water or rubbing alcohol and a soft cloth to remove couplant from the acoustic window (or face) of the probe. Failure to do so may scratch the acoustic window. During disinfection immerse the probe up to, but not including, the colored cable bend relief. Always snap the needle guides on to the probe hook. Do not slide the needle guide on to the needle guide hook, as the sterile probe cover may tear. The adverse biological effects of ultrasound on tissue appear to be threshold effects. When tissue is repeatedly exposed to ultrasound, with intervals in between, there will likely be no cumulative biological effect. If, however, a certain threshold has been passed, biological effects may occur. While the Site~Rite IV acoustic output parameters fall well below all FDA thresholds for adverse biological effects, any given Ultrasound Procedure should be performed using the principle of ALARA (As Low As Reasonably Achievable). The licensed medical practitioner should limit the time of patient exposure to ultrasonic radiation using the principle of ALARA. Only accessories that are approved for use by country and local authorities are to be connected to the Site~Rite IV Scanner. Use of accessories that are not compliant to International Electrical Safety Standards may result in device failure. Use only Bard Access Systems cleaning and disinfection procedures. Failure to do so may damage the device. Notes Note: Note: Note: Note: Note: Note: Note: If you are using the A/C adapter, the adapter automatically adjusts to the correct line voltage between 100 - 240 VAC, 50 - 60 Hz. The adapter ships with country-specific wall plugs. Verify that the A/C adapter has the appropriate plug for your country's electrical system. The probe connector can only be inserted in one direction. If the connector does not fit into the probe port, turn the connector over and try again. When in the screens to change the day and time; to discard the changes made to the time and date, press the Freeze Frame button before saving the changes. The date format does not change. When cleaning the system and components, it is important to remove all particles or other matter from all surfaces and crevices. For periodic probe testing, you may use a deeper intersect guide than 1.5 cm, with the 7.5 MHz probe, or a shallower intersect guide, 0.5 cm or 1.0 cm, with the 9.0 MHz probe. When placing a cold battery in a warm room to charge, the rapid temperature change of the battery occasionally causes the Site~Rite Mini Battery Charger to switch from the Rapid Charge mode to Pending Charge mode (within a few minutes of turning on). If this occurs, remove the Site~Rite Mini Battery Charger from the ACpower and remove the battery from the molded battery charger connector. Wait a few moments before reconnecting the Site~Rite Mini Battery Charger to AC power and the battery to the molded battery charger connector. Use of the battery packs in low temperatures reduces battery life. iv Site~Rite* IV Ultrasound System - TECHNICAL MANUAL MATERIAL Safety Data STANDOFF PROBE FLUID Warning: Contains n-Butyl Phthalate (C16H22O4): Causes eye irritation.

The Site~Rite IV Transducer Assemblies are NOT field serviceable. When it is determined that a transducer assembly is damaged or defective, the transducer assembly MUST be returned to Bard Access Systems for service. Opening, disassembling, modifying or tampering with any transducer assembly will void the warranty. Bubbles may develop in the transducer assembly fluid. If a bubble becomes large enough to be seen in the scan image, the transducer must be returned to Bard Access Systems for service. Opening, disassembling, modifying or tampering with any transducer assembly will void the warranty. SITE~RITE* IV SYSTEM DESCRIPTION Site~Rite IV System has four major components (see Figure 1): · Power Source (Battery Pack or Alternating Current [AC] Adapter) · Transducer Assembly · Scanner Assembly · Site~Rite Mini Battery Charger Figure 1 - SITE~RITE* IV System Block Diagram Site~Rite* IV Ultrasound System - TECHNICAL MANUAL Power Source The Power Source supplies +14.4 Volts Direct Current (VDC) (nominal) to the Scanner Assembly. An AC Adapter supplies +15 V Direct Current (VDC) to the Scanner Assembly. Each device snaps onto the rear of the Scanner Assembly. The AC Adapter permits system operation with the unit plugged into a wall outlet. The battery permits portable system operation. AC Adapter The AC Adapter provides +15.0VDC (nominal) to the Scanner Assembly. It snaps onto the rear of the Scanner Assembly, occupying the battery position. The adapter is a switching power supply that converts AC line voltage to the Direct Current (DC) voltage required by the system. The United States adapter accepts 110 Volts Alternating Current (VAC) (nominal), 60 Hertz (Hz) power. The European adapter accepts 230VAC (nominal), 50 Hz power. See Site~Rite IV Ultrasound System Specifications for the actual input voltage range. The AC Adapter is NOT field serviceable. When it is determined that an AC Adapter is defective, the adapter MUST be returned to Bard Access Systems for repair. Opening, disassembling, modifying or tampering with any AC Adapter will void the warranty. Battery Pack The Battery Pack (see the drawing on Page B-12) provides +14.4VDC (nominal) to the Scanner Assembly. It snaps onto the rear of the Scanner Assembly like the AC Adapter. The pack, when fully charged, can operate the system for approximately two hours. The Battery Pack contains 12 nickel-metal hydride cells, connected in series. A resettable poly switch provides over current protection. A Pepi* N-1 thermostat provides over temperature protection. A thermistor attached to the cells provides real-time temperature data to the charger during the charging cycle. The Battery Pack is sealed and cannot be serviced. Warning: Always properly dispose of dead battery packs in accordance with local regulations. Improper disposal may pressent an environmental hazard. Transducer Assembly The Transducer Assembly has three basic components. These are: · Piezoelectric Transducer · Motor · Housing and Cable Assembly The transducer converts electrical pulses from the Pulser/Receiver PCB into acoustical pulses. These pulses penetrate the target. Pulse echoes, from the target, return to and strike the crystal transducer. The transducer converts these acoustical echoes to electrical signals. The electrical signals are sent to the Pulser/Receiver PCB. Site~Rite* IV Ultrasound System - TECHNICAL MANUAL The transducer is mounted to the rotor of an oscillating motor (see Figure 2). As the rotor oscillates it positions the transducer. At intervals the transducer emits acoustical pulses (see Figure 3). This establishes the scan sector. Transducer assembly fluid encapsulates the transducer and motor, improving ultrasound signal transmission. All of these components are contained in the transducer assembly housing and connected to the scanner assembly with the cable assembly. Figure 2 - Motor - Transducer Configuration Figure 3 - Transducer Motor Oscillation Site~Rite* IV Ultrasound System - TECHNICAL MANUAL Scanner Assembly The Site~Rite IV Scanner Assembly consists of nine major sections (see Figure 4). These include: · Power Supply Printed Circuit Board (PCB) · Digital PCB · Pulser/Receiver PCB · Servo PCB · Motherboard · SODIMM · User Interface PCB (Button Board) · LCDPCB · LCD Assembly Figure 4 - SITE~RITE* IV Scanner Block Diagram POWER SUPPLY PCB The Power Supply PCB (see Figure 5) generates most of the operating voltages required by the system from an external source. The source is either the AC Adapter or the Battery Pack and provides interface between user control (Button Board) and Digital PCB. The power supply PCB has a microprocessor that monitors button inputs and battery condition. Upon receiving a power button press, the processor will activate the front panel light and relay that governs the power for the rest of the scanner. The processor will also detect other button pushes and communicate accordingly with the digital PCB. Once the low / dead battery sense circuitry has confirmed a change in condition, the processor will be notified and will blink the LED (for low battery) or turn off the relay (for dead battery). Site~Rite* IV Ultrasound System - TECHNICAL MANUAL Figure 5 - Power Supply Block Diagram The Power Source output is connected to the Input Filter where it is Electro-Magnetic Coupling (EMC) and Electro-Static Discharge (ESD) filtered. Additional EMC and Electro-Magnetic Interference (EMI) filtering takes place at the input and output of each section of the power supply. The Low/Dead Battery Sensing section signals the CPU to flash the Power Button Light Emitting Diode (LED) when the Power Source voltage falls below +13.7VDC. A dead battery system shutdown occurs when the Power Source voltage falls to +12.5VDC. The -10VDC Supply provides -10VDC for the Pulser/Receiver PCB. This supply uses a charge pump setup. The output of the charge pump is filtered and regulated. The +5VDC Supply provides +5VDC to the Digital PCB. This supply uses a high efficiency 3Ampere (A) switching regulator. The +12VDC Supply provides regulated +12VDC to the Pulser/Receiver PCB. Digital PCB Figure 6 - Digital PCB Flow Chart Note: The SODIMM's pictured in Figure 6 are located within the SODIMM Module. The Digital PCB is the core of the Site~Rite IV Ultrasound System, controlling and monitoring all aspects of system operation. The system CPU (Central Processing Unit) is located on the Digital PCB. The CPU performs the following functions. It controls and monitors ultrasound generation, reception, and data acquisition; creates and maintains a one bit deep video overlay plane for the text, icons, and dot markers on the display; and controls the scan converter that uses the acquired ultrasound data to create an ultrasound image. The Digital PCB also performs some housekeeping duties, adjusts systems operation as directed by the operator through the Buttons PCB and controls three Logic Cell Arrays (LCA's) located on the board. The LCA's perform much of the real work for the CPU. Site~Rite* IV Ultrasound System - TECHNICAL MANUAL Front End LCA The Front End LCA performs two functions: · Glue logic for the CPU, Random Access Memory (RAM), Flash Memory, etc. · Performs ultrasound data acquisition Transducer motion initiates the ultrasound data acquisition sequence. The threshold voltage in the Threshold Digital to Analog Converter (D/A) is compared to the transducer position signal voltage, or Absolute Position Output (APO). When APO voltage crosses the threshold voltage the data acquisition sequence is triggered. The ultrasound data acquisition sequence contains the following events: 1 The Pulser is fired, generating an ultrasound pulse. 2 A new threshold is established. 3 The Pulser is recharged. 4 The receiver is activated. 5 Time Gain Compensation (TGC) circuits are swept through their sequence. 6 The Ultrasound A/D and the First-In-First-Out (FIFO) memories are clocked to acquire the data. 7 The receiver is deactivated. Video LCA The Video LCA generates the video timing, based on the SODIMM data, and moves the ultrasound data from the FIFO's into the Static Random Access Memory (SRAM) and moves the SRAM data to the Filter LCA, as needed. The SRAM's store the ultrasound data currently displayed by the video output stream. Filter LCA The Filter LCA performs a two dimensional interpolation to convert the ultrasound data to pixel data in the video stream. This is necessary because the ultrasound data is formatted in polar coordinates while the pixels are formatted in Cartesian coordinates. The interpolation coefficients are stored in the half of the SODMM's that is connected to the Filter LCA. It also performs the required calculations to add the overlay to the video signal, as well as the sync and blanking levels. These activities are controlled by the Video LCA and the timing data contained in the SODIMM's. PULSER/RECEIVER PCB The Pulser/Receiver PCB (see Figure 7) generates, receives and conditions the ultrasound pulse prior to digitization and display. This PCB contains 11 sections. The ultrasound pulse is produced when the Pulse Generator applies a drive signal to the transducer. This pulse travels through the target medium, causing return echoes of varying intensity. The density of the target medium determines the intensity of the echoes. The transducer receives the echo and sends the pulse to the Amplification and Impedance Matching section. The pulse passes through several stages of amplification and filtering where CPU-controlled modi- fication of the various pulse parameters (overall gain, Time Gain Control [TGC], far field gain and baseline) is accomplished. The pulse passes through detection/ rectification and is again amplified. During the last stage of amplification, edge enhancement and low frequency gain are applied, based on the specific Transducer Assembly connected to the system. The pulse is finally sent to the Digital PCB for digitizing. Figure 7 - Pulser/Receiver PCB Flow Chart Site~Rite* IV Ultrasound System - TECHNICAL MANUAL SERVO PCB Figure 8 - Servo PCB Flow Chart The servo control circuit provides motor drive power for the transducer assembly and receives the position sensing signals from the transducer assembly. The circuit generates required voltages locally from switched, filtered system power. The circuit provides probe auto zero and soft start at power up. The output of the B-Mode Command generator is a round peak triangle wave with symmetrical positive and negative peaks. The amplitude and frequency of the command waveform are both adjustable. B-Mode Command is generated and supplied to the Automatic Gain Control (AGC) and Auto Center Circuitry. The auto center circuitry forces the transducer to the 0° position on startup and controls the time required for the transducer to reach full motion (typically 1 to 3 seconds). AGC ensures that the commanded scan angle is symmetrical. Using zero crossing detection, feedback from the Position Sensing circuitry is combined with the B-Mode Command and sent to the Error Amplifier circuitry to provide position and drive level correction to the motor drive circuitry through a filtering circuit. Transducer motor current is monitored to prevent and notify the operator of an over current condition. SODIMM MODULE The SODIMM Module contains non-volatile memory devices. They store interpolation coefficients (weights) and control data for the filter and video LCA's. Module capacity allows the display of any of the four discreet shapes on the screen. BUTTON PCB The Button PCB is a used to create the user interface. A 20-conductor flat ribbon cable connects the Button PCB to the Mother Board. The button and LED signals are transmitted through the Mother Board to the Power Supply Board where the Microcontroller monitors the buttons and controls the LED. The board consists of nine contact areas where the conductive "pills" on the back of the rubber buttons touch to complete the appropriate circuit when a button is pushed. A LED in the PCB is illuminated during normal scanner operation. That same LED is flashed slowly to indicate a low battery condition. It is also used to blink out error messages when needed. LCD PCB The Liquid Crystal Display (LCD) PCB is an interface between the Digital PCB, which generates the digital data signal that will become the image data, and the LCD screen. The LCD PCB controls the LCD backlight via one digital and one analog signal from the Digital PCB. The LCD PCB also acts as a mount for the LCD screen, which is attached to the LCD PCB. The LCD PCB is attached to the motherboard PCB via a 40-conductor flat ribbon cable.
